How to install dbgsym to AWS Server?

I would like to use SystemTap to debug in AWS Linux server

here is my AWS Linux server kernel version

root:/# uname -r
5.11.0-1019-aws

I know that I need to install dbgsym to help me do the debug, I had searched this link

https://launchpad.net/ubuntu/+search?text=linux-image

I found there is a package which might I need linux-image-5.11.0-1019-aws-dbgsym.

But I have no idea how to add this package or install it on my computer.

First, I use apt-get update and apt-get install linux-image-5.11.0-1019-aws-dbgsym to install that, but it can't be found.

root:/# apt-get install linux-image-5.11.0-1019-aws-dbgsym

E: Couldn't find any package by regex 'linux-image-5.11.0-1019-aws-dbgsym'

I had tried to use PPA but still fail.

root:/# add-apt-repository -s ppa:ubuntu/linux-image-5.11.0-1019-aws-dbgsym
Cannot add PPA: 'ppa:~ubuntu/ubuntu/linux-image-5.11.0-1019-aws-dbgsym'.
ERROR: '~ubuntu' user or team does not exist.

Is there any way I can install linux-image-5.11.0-1019-aws-dbgsym to my AWS server?

Thanks.
